Most organizations are currently engaged in application modernization initiatives, transitioning from monolithic applications to container-based ones using a microservices architecture. This transformation aims to enhance agility, scalability, and maintainability in software development and deployment processes. However, migrating from a monolithic to a microservices-based application can present challenges, especially when dealing with dependencies like specific libraries or drivers exclusive to Microsoft Windows.

To address these challenges, Red Hat OpenShift offers solutions for running legacy applications, such as leveraging OpenShift virtualization to operate Windows virtual machines alongside containerized applications. Additionally, Red Hat provides .NET Core base container images on Red Hat Enterprise Linux (RHEL), utilizing the Universal Base Image (UBI) to facilitate the development and deployment of .NET Core applications in containerized environments like OpenShift and Kubernetes.

Furthermore, Red Hat OpenShift supports running Windows containers on Windows worker nodes, enabling organizations to harness the vast Kubernetes ecosystem of tools, integrations, and community support to enhance the capabilities of their Windows workloads. Since version 4.6, Red Hat OpenShift has incorporated Windows worker nodes support, initially introduced as a community operator.

For persistent volume storage requirements, Windows containers, like their Linux counterparts, necessitate adequate storage solutions. However, Windows worker nodes have limited Container Storage Interface (CSI) driver support. This guide elaborates on utilizing the SMB CSI driver and Windows CSI Proxy to enable persistent volume storage provisioning for Windows containers operating within the Red Hat OpenShift environment.
